	* libgimp/gimpui.def: Add missing entry points.

	* plug-ins/common/plugin-defs.pl: Mark bz2, mail, screenshot and
	url as optional (not built on Win32). Ditto for winclipboard and
	winprint (Win32 only).

	* plug-ins/common/mkgen.pl: Use -mwindows on Win32.

	* plug-ins/common/Makefile.am
	* plug-ins/common/.cvsignore: Regenerated.

	* configure.in: Correspondingly conditionally define BZ2, MAIL,
	SCREENSHOT, URL, WINCLIPBOARD and WINPRINT, and AC_SUBST them.
	Set XJT to empty always on Win32 (uses tar, mv and bzip2, which
	aren't usually available).
